Re: 6.0 Fortivoice upgrade
My biggest headache was call routing. There was an undocumented change that fouled up my calls and at the same time brought an external problem to light.
I'm using an FVG-GO08 with 7 analog lines. In 5.3 outbound calls routed out starting at line 1, working their way to line 7. Knowing this, I purposely put my incoming round-robin AT&T lines as 5-7 so that my outbound calls would only rarely spill into my incoming lines.
In 6.0, outbound call routing reversed to start at line 7 and work their way back to line 1. So now, outbound calls were immediately tying up my incoming call lines. Bright side is this led me to find that one of my incoming lines from AT&T was not working.
Hopefully this routing change gets added to the release notes so others don't have the same problem.
